Something is up with two factor authentication code. Some days I get it other days I don't? Changed my password received code for a couple of days. Now not receiving again. This is getting ridiculous.
Use one of your backup codes.
@littledebskis: Are you saying that you are being asked for the two factor authorization (2FA) code every time you log in and sometimes you do not receive the text, or that you are not receiving the 2FA challenge on each login?
